I found the Townsend Family Tree, trees.ancestry.com/tree/31933909/person/18389282180 which contains a Robert Harrison Baker b. 23 April 1917 in Glentana, Valley, Montana and died 24 June 1950 in Alaska.
His parents are listed as Chester Earl Baker b. 1890 and d. 1957 and Marion Hattiner b. 1897.
No wife or child is shown on this tree.
You can't take info on a family tree at face value but it does give you a place to start looking. I looked up the following Census info and maybe something here will help.
